Comparison Of Visual Outcomes In Presbyopia Intraocular Surgery Before And After A Biometry Training Program

To measure and report on the level of improvement in safety and efficacy outcomes after implantation of TECNIS Synergy IOL following a specialised biometry training program provided by the manufacturer.

Private Refractive Surgery (Optical Express)

Outcomes are reported on 813 patients, 1332 eyes, who underwent lens surgery prior to a biometry training program compared to 1,057 patients, 1,469 eyes, who were treated post training. Demographic and preoperative parameters were well matched between the two cohorts. The age range of patients was 40 to 83 years, with pre-op refractive range of +11.00D to -9.75D and up to -3.50D of manifest astigmatism. 

Binocular UCDVA 20/20 (6/6) or better was achieved in 77.5% of ICB patients implanted prior to training compared to 84.1% post training (p<0.01). 98.5% of patients pre training reached 20/40 (6/12) or better; 99.8% post training (p<0.01). Binocular UCIVA 20/40 (6/12) or better was achieved in 99.7% of patients pre training compared to 99.0% post training (p=0.19). Binocular UCNVA N8 or better was achieved in 98.7% pre training compared to 98.8% post training (p=0.81). Patient reported satisfaction was high for both cohorts; 94.7% for pre training and 97.8% post training (p<0.01). Quality of Vision difficulty was comparable between cohorts, while a meaningful reduction in severity was observed in the post training group (p<0.01).

The TECNIS Synergy IOL provides a safe and effective full continuous-range-of-vision for patients seeking spectacle independence. Clinical and patient-reported outcomes suggest that the implementation of a specialised biometry training program may help improving both quantitative and qualitative distance visual outcomes. Longer follow-up is warranted to confirm findings.
